Planned Learning Activities and Teaching Methods

The course shall be given as lecture, class presentations and discussion format. All class members are expected to attend both the lecture and seminar hours and take part
in the discussion sessions. Besides taught lecture, group presentations are to be prepared by the groups assigned for that week and presented to open a discussion
session.
